Title:
CLOTHES TREATMENT DEVICE AND CONTROL METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/068063
Kind Code:
A1
Abstract:
Embodiments of the present application provide a clothes treatment device and a control method thereof. The clothes treatment device comprises an outer drum, an inner drum, a balancing apparatus, a water injection assembly, an eccentricity detection unit, and a main control board. The balancing apparatus comprises multiple water tank assemblies arranged along the circumference of the inner drum and connected to the inner drum. Each water tank assembly has a drainage port. The eccentricity detection unit is used to detect load eccentricity information of the inner drum. The main control board is configured to determine, according to the load eccentricity information, a water tank assembly awaiting water injection, and control the water injection assembly to inject water into the water tank assembly. In a spin-drying process, regardless of the rotation speed, when the inner drum needs to be balanced, the main control board controls the water injection assembly to actively inject water into the water tank assembly. The combined mass of the injected water and the overall mass of the water tank counteract the eccentric load mass of the inner drum, enabling the inner drum to be well-balanced over the full range of speeds thereof, thereby effectively reducing the risk of drum collision and reducing vibration and noise.
